Let's break this down. We're going to add 286 and 2200 together.

Step 1: We'll start by adding the digits 6 & 0 in column 1 and get 6.

Step 2: We'll start by adding the digits 8 & 0 in column 2 and get 8.

Step 3: We'll start by adding the digits 2 & 2 in column 3 and get 4.

Step 4: We'll start by adding the digits 0 & 2 in column 4 and get 2.

So, 286 + 2200 = 2486.
